hey i have just a plan stock old 89 RS 305 tbi, i was wondering what u gusy think the best stall converter is (i think thats what it is called) i hear people with 2000 stall, and u hear 2400 stall a lot, whats the best for me, i'm not gonna be racing or anytihng, i just want to gain my horsepower i have quicker

 

Running the stock cam I would say anwhere from 2000rpm to 2400rpm would be good. If you do go with a higher stall converter you should also look into a trans cooler.

 

i would say closer to 2000 unless you have done some good mods like headers/exhaust and some engine work like intake and cam . then i would go for around 2400 ro so.

 

abnd defintly get a good trans cooler if you swap oput the stock convertor or you will fry your trans in no time..

 

If you're not gonna be doing any racing...then why the hell would you want a higher stall? If you want just a little more power, do something simple like an exaust and K&N.

 

i think it is time to once again point out the difference between hp and et.
power is what creates mph at teh track. that has very little to do with your et though. et is the way you show your car is using it's power. with proper hook and gearing a car taht runs a lower mph will beat a car that has more power but is less prepared.
that being said, a torque convertor does not add any power at all. it just allows the car to take advantage of the power iun the engien better. that means the car will be qiuicker, but still run the same mph.
2000rpm is a very small step above stock, you won't se much of a gain from it. 2400 is a great stall speed because it allows the car to leave the line using the thickest part of it's torque band and will give you a much larger gain.

That's what i was saying in not so many words. a TC wont give the car HP, so it's not something you can use in everyday normal driving all across the board. A TC is only gonna benifit him in racing....unless he just likes taking off hard from lights. But now an exaust or such is something that will give you a gain in all forms of driving. It would be a waste of his time and money....if he's not gonna race as he says.

 

The only reason I got the high converter was to cut my et down. Of course when I ran out of money I couldnt get any more suspenion mods so I wont be able to stall that high anyways

 

A TC is a hell of a way to cut down ET...but this guy says he doesn't race

 

I would think a plain stock L03 engine would be fine with the 95 S10 4.3L converter since most of the L03's power is on the bottom end anyway. S10 converter stalls between the 2000 and 2400 mark and isn't too expensive. Then use some of that money replace the entire exhaust system and maybe a decent gear with posi.

 

24202310 vortec S10 converter

Its supposed to stall to 2200 in a 305. $200 from gmpartsdirect.com or a good dealer like Sam Smith... It'd definatlly be my second choice if I didnt go with the B&M.

 

what size is the stock converter, in the th700r4 lo3 setup.

 

How much does the installation of a TC cost?

 

a 6cyl s-10 convertor will stall around 2200-2400, a 4cyl s-10 convertor will stall around 2400-2800. i believe teh 4-cyl one ios teh same price and woudl be a parger performance gain.
our stock convertor will stall 1300-1400, i think the tpi cars were supposed to a get slightly higher stall speed, but i have never seen any confirmation of this.
a straight tc swap will take a few hours in a shop. figru eat least 2 hours iof not 3. shop rates are usually 65-80 an hour plus what ever fluids you need to get it back together.
you can do a tc swap your self at home in a day if you want.

Most definatlly could be done in a day.

Take the cover off under the tcc. Unbolt the drive shaft, unbolt the flywheel bolts, support the tranny and the back of the engine, unbolt the tranny from the back of the block, slide the old tcc off, slide the new one on (rotate it, it'll slide on, then you'll rotate it and it'll click, rotate more and it'll click again. Its very important to get both clicks.) bolt the tranny back up, bolt the fly wheel back on, bolt the drive shaft back on.

Or you could just side it on when the engine / trans is already out

 

would a 2200-2400 stall converter hurt mpg any. Or only realy affects car when at wot from a stop.

 

It will affect gas mileage...how much, I don't know.

If I could do it all over again the first thing I would do to my godforsaken RS would have been a 2400 RPM stall TC and a posi unit.

The gas thing shouldn't be too bad, especially with those excellent 2.73's out back.

 

ttt , would 2400 stall converter hurt gas mileage?And if so by how much

 

it won't bother it much, maybe 1 or 2 mpg aroudn town. it won't change your highway or cruising mileage at all.

Tim, you're the man. Every time i have a question, whether its cams or TC's, you know the answer. Do you have a sister? lol, j/k.
